The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts. Those of ordinary skill in the art will realize that the following detailed description of the present application is illustrative only and is not intended to be in any way limiting. Other embodiments of the present application will readily suggest themselves to such skilled persons having benefit of this disclosure.

In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with application-related and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.

Portable electronic devices (e.g., laptop computers, smartphones, notebooks, tablets, cameras, etc.) having two displays (e.g., a secondary screen) are provided by the present disclosure. The screens are connected through a hinge or joint allowing them to rotate relative to one another.

In some embodiments, the disclosure provides a secondary screen for devices like smartphones, notebooks, tablets as well as digital cameras is proposed. The device equipped by the secondary screen may have a form factor of a clamshell (flip). The sections may be attached to each other on long or on a short edge of the device. The angle between the sections may reach 360° , when the screens are oriented in the opposite directions. The sections may be detachable. The secondary screen(s) of may be used to demonstrate the output of the photo/video camera(s) of the device. Digital camera may be also equipped with the secondary screen(s). The secondary screen(s) is/are used to demonstrate the picture from the camera to the person(s) being shot or to somebody else located at some distance. On the second screen or as separately functioning software (or additional software functionality, implemented into programs MICROSOFT WORD or EXCEL, or other programs such as ADOBEREADER) for touchscreen/touch-surface device(s) the user-adjustable keyboard can be used. Size, position, function and shape of any button may be specified by the user.

Referring to FIGS. 1 and 3, in some embodiments, the screens (e.g., screens 102 and 104 in FIG. 1 and screens 302 and 304 in FIG. 3) of the portable electronic device are arranged in a clamshell orientation, joined at a hinge (e.g., hinge 106 in FIG. 1 and hinge 306 in FIG. 3) such that one or both of the screens are rotatable about the hinge. In some embodiments, as illustrated in FIGS. 1 and 3, the screens are attached to each other through a hinge disposed along a long edge of each screen. In other embodiments, the screens are attached through a hinge disposed along a short edge of each screen. In some embodiments, the sections (e.g., screens) can be fixed at any angles/positions relative to one another. In some embodiments, the angle between the sections (e.g., screens) may reach 360°, when the screens are oriented in the opposite directions (e.g., as shown in FIG. 1 when the screens are at positions 102-4 and 104-4, respectively, and as shown in FIG. 3 when the screens are at positions 302-0 and 304-0, respectively).

Referring to FIG. 2, in some embodiments, the screens (e.g., screens 202 and 204) of the portable electronic device are joined at a joint (e.g., joint 206) attached to a single point on each screen (e.g., at a corner of each screen). In some embodiments, when the screens are joined at a single point, the screens may rotate about more than one axis relative to each other. For example, as illustrated in FIG. 2, screen 202 rotates away (e.g., along an x-axis) from screen 204 and then twists (e.g., along a z-axis) to face left, when moving from position 202-1 to position 202-2.

In some embodiments, the two screens are in wired communication (e.g., one display is in electronic communication with one or more processors located in a housing to which the other screen is mounted) through a connection (e.g., communication bus) spanning the hinge or joint connecting the two screens (e.g., through a communication bus passing through hinge 106 in FIG. 1). In some embodiments, the two screens are in wireless communication with each other. In some embodiments, one screen is detachable from the other and the screens are in wireless communication when detached. In some embodiments, where one screen is detachable from the other screen, the screens are in wired communication when attached (e.g., the hinge or joint attaching the two screens includes a communications docking mechanism bringing the two screens into wired communication with each other).

In some embodiments, one screen is powered by a power source located within a housing to which the other screen is mounted, and a connection to the power occurs through the hinge or joint connecting the two screens. For example, in some embodiments, screen 26 mounted to housing 2 is powered by power source 24 within housing 1, through a connection transversing hinge 62, as illustrated in FIG. 5.

Referring to FIG. 4, in some embodiments, a photo, live image, video, etc., captured by a digital camera within a dual-screen electronic device of the disclosure is transmitted to one or both of the two screens (e.g., screens 404 and 402). For example, as illustrated in the upper left panel of FIG. 4, where the screens are positioned back-to-back relative to one another (e.g., at an angle of about 360° relative to a closed configuration where the two screens are directly facing one another), the person(s) 408 who is the subject of the photo/video to view the image at the same time as the person 410 taking the image. This allows the subject 408 to see how they look in the photo and/or video (e.g., to assess the quality of shooting). If the screens are detached, as illustrated in the other panels of FIG. 4, one screen 404 can be located in view of the person(s) 408 who is the subject of photo/video. This allows the subject to see how they look in the photo and/or video (e.g., to assess the quality of shooting) when not looking in the direction of the digital camera (e.g., within the housing to which screen 402 is mounted). For example, in the upper right panel of FIG. 4, subject 408 can view (e.g., in real-time) an image being acquired by a digital camera associated with screen 402, while facing away from the camera, by looking a second screen 404 that is detached from screen 402. The device is unique for photo and/or video shooting. For example, when taking a “selfie”, the detachable secondary screen may be attached to the opposite side of a selfie stick (e.g., near the user) to allow the user to see the image being acquired. In some embodiments, more than one secondary screen may be used, e.g., positioned at different locations and angles relative to a subject being acquired. This allows them to see their image without turning their head(s)

In some embodiments, a secondary screen(s) may be used with photo/video cameras for the same purposes and in the same way (in some embodiments, the photo/video camera will include a first display mounted on the camera). In this case the secondary screen(s) should be detachable or provided as separate detail(s). The secondary screen(s) may be of a bigger size. The secondary screen(s) allow(s) the person(s) being shot to estimate the quality of shooting. If the secondary screen(s) is/are big enough it may be located near the photographer/camera man or even behind him. Such device will be very helpful for professional photographers, film makers and for models (e.g. fashion models being shot). Several (more than one) secondary screens may be used in this case as well. They may be located at different directions/locations around the photographed/filmed person.

In some embodiments, on the second screen or as separately functioning software (or additional software functionality, implemented into programs MICROSOFT WORD or EXCEL, or other programs such as ADOBEREADER) for touchscreen/touch-surface device(s) the user-adjustable keyboard can be used (e.g., to use for composition of a document displayed on the first screen. In some embodiments, the size of the electronic keyboard displayed on the second screen can be enlarged or shrunk by a user, e.g., to configure the keyboard to the size of the user's hands. This will reduce the number of misprints caused by hitting a wrong button and/or provide possibility of quicker typing as soon as sizes of keyboard buttons and their locations are adjusted under exact user. In some embodiments, more than one secondary screen can be used to display one or more electronic keyboards.

In some embodiments, each key on the electronic keyboard is individually customizable. In some embodiments, the size, position, color, and/or shape of any button(s) may be specified by the user. In some embodiments, when a single key on the keyboard is customized by a user, the device automatically customizes one or more other keys on the keyboard in a similar fashion (e.g., all keys on the keyboard, all number keys, all letter keys, all punctuation, etc.).

In some embodiments, one or more user-defined keys may be added to the electronic keyboard. In some embodiments, a user-defined button is associated with one or more of the following functions:

-   -   entering non-standard symbols (mathematical, physical,         financial, letters or pictograms from different languages);     -   launching different programs and/or commands;     -   launching macros (e.g., sequences of programs and/or commands);     -   any menu button of any program may be appointed/converted into         button of the adjustable keyboard; and     -   any button of the adjustable keyboard can be provided with any         number of switchable symbols/commands.

In some embodiments, the screen displaying an electronic keyboard also displays a specified portion of the document being drafted on the other screen (e.g., a portion of the document being composed/edited).

In some embodiments, the secondary screen, or a portion thereof, is configured as a touch-pad to direct a cursor displayed on the primary (e.g., other) screen. In some embodiments, the size of the touch-pad area (e.g., the portion of the display dedicated to act as a touchpad, speed of mouse-pointer in different zones) is adjustable by the user.

Other screen(s) may also be located on the place of any other surface(s) without screen(s). In some embodiments, the device with a secondary screen(s) can be made of two (or more) independent devices. They may have a possibility to be connected to each other by a kind of join/hinge and/or may have only wireless connection. One of the devices functions as the secondary screen. In this case special software is required.
